zenon is a software platform from COPA-DATA for industrial and energy automation. Manufacturing companies and energy distributors use it as a SCADA and HMI system: it records data from equipment, lets operators control machines and plants, and feeds business-intelligence applications. Optional parts include zenon IIoT Services for networking equipment across sites, zenon Historian 360 and the straton embedded soft PLC. zenon is commercial, closed-source software that customers install and run themselves.
COPA-DATA is headquartered in Salzburg, Austria. The company describes itself as independent and family-owned: the Punzenberger family bought back all external shares in 2006, and no non-European parent company is involved. Because zenon is installed on the customer's own servers and devices, process data stays in the customer's environment unless optional services are added; where those optional services are hosted is not documented on the pages consulted. For European plant, utility and building operators, zenon is a European-built alternative to US SCADA platforms such as Ignition.
